Scottish
(1723 – 1790)
“……The Wealth of Nations”
Division of Labour
Increases productivity
and a country’s wealth.
Invisible hand of
competition
Allows self regulation
to operate ensuring
economic progress
Eg. it takes 18 different
operations to make a pin!
Labour theory of
value & wealth

equal to the amount of
labour that goes into
producing it

No justification for
government
intervention except

“The Principles of Population”
Theory of
Population & Food
•Population grows
geometrically (2,4,8,16,32).
•Food grows
arithmetically (1,2,3,4,5,6).
•If population not kept in
check famine & disease
would result.
•SOL did not fall in 19th C
but his ideas were more
relevant in the population
explosion of the 20th C
Applied the Law of
Diminishing Returns to
Land
•Best land taken up
first, then next best,
then inferior….
•At each stage the
amount of food is less
than before.
Iron Law of Wages
An increase in wage above
subsistence level
= increase in population
= increase in supply of
labour
=decrease in wage
David Ricardo
Economic Rent
•If population
increases inferior land
used.
•For use of land rent
was paid.
•Cost of producing on
the best land was
lower.
•Food produced on
good land earned a
surplus over that
produced on inferior
land.
•This surplus led to an
increased rent
payable for the use of
good land.
Classical Economist
English
(1772-1823)
“The Principles of Political
Economy & Tax”
Law of
Comparative
Costs/Advantage
•Supported idea of
free trade.
•A country should
specialise in the
production of those
goods in which it is
relatively most
efficient .
•And trade for the
remainder of it’s
reqiuirements.
Accepted the Subsistence Wage Theory
He agreed that an
increase in wage above subsistence level
= increase in population
=decrease in wage
Jean Baptiste Say (1767-1832)
Wrote: “Treatise on Political Economy”
Says law
• “Supply creates it’s own demand”.
• People make products they are most
efficient at.
• They exchange their surplus for money.
• They use this to buy goods that they want.
• Therefore the supply of goods creates a
demand for goods.
John Stuart Mill (1806-1873)
Wrote: “Principals of Political Economy…”
• He advocated the following;
1. Demand & supply were important in
assessing the value of a product.
2. Law of diminishing marginal returns.
3. Predicted the emergence of dominant
firms.
4. Establishment of trade unions to
counteract the power of dominant firms.
Mill became disillusioned by the capitalist system & began
to lean towards a mild form of socialism.
“Nothing can be done for Ireland without
transforming the rural population from cottier
tenants into ….land proprietors (owners)”.
JS Mill, “Principles of Political Economy” (1848)
“Lessons in ingenuity
from the Victorian
age.”
The Socialists
• Karl Marx (1818-1883)
Written
by
K. Marx
Karl Marx
Socialist
German
(1818-1883)
“The Communist Manifesto”
Labour theory
People required to work
more hours than
necessary to generate
the income needed to
pat their wages.
Profit
Labour produced a
surplus value which was
profit for employers
Predicted
Growth of oligopolies
Forecasted
Emergence of trade
cycles
Social revolution
Where proletariat
would take public
ownership of the FOP
Profits invested in
technology
Reduced need for
labour = unemployment
Two tiered society
=unequal distribution of
wealth
Capitalists (owners)
Proletariat (workers)
Criticism of
Karl Marx
• The growth of unions ensured protection of working
class.
• Middle & professional classes emerged.
• Technology did not lead to mass unemployment.
However
• Predictions on oligopolies & trade cycles came true.
The Neo-classical Economists
• Alfred Marshall (1842-1924)
Theory of Value
The value of an item is determined;
•SR by utility and demand
•LR by cost of production
Alfred Marshall
Neo-classical
English
(1842-1924)
“The Principles of
Economics & Money,
Credit & Commerce”.
Quasi Rent
Economic rent earned
by FOP in SR when D>S
Consumer Surplus
Growth of monopolies
could be prevented by;
•Gov regulation
•Consumer information
•More accountability
Distribution of income/wealth
The return to each FOP is determined
by their marginal utility
The difference between
what a consumer actually
pays for a good and the
maximum
which
he/she
would have been willing to
pay rather than going
without it.
Price-elasticity of demand
Quantified buyers’
sensitivity to price
changes
Marshall’s scissors analogy.
• Demand & supply are interdependent
just like the blades of a scissors.
Keynesian Economists
• John Maynard Keynes (1883-1946)
Favored government
intervention
•It is the job of the
gov to run the economy
•Gov can use fiscal
policy (any action taken by
the gov which alters current
revenue & exp) to create
full employment
John Maynard Keynes
Keynesian
British
(1883-1946)
Liquidity
preference theory
“The General Theory of
Employment, Interest & Money”
3 reasons (motives)
for holding money
•Transaction motive
•Precautionary
•Speculative
(See chap on capital)
If Inv<Saving=Leakage
Leads to a decrease in
national income &
employment
Investment decisions
Depends on
expectations not rate
of interest
The multiplier
Shows the relationship between an initial injection into the circular
flow of income and the eventual total increase in national income.
The Monetarists
• Milton Friedman (1912-2009)
Monetary policy
Should be the main
instrument used by
the government to
manage the
economy.
Milton Friedman
Monetarist
(1912 -2009)
“A Monetary History of the US”
(Actions taken by the
gov/ECB which
influences the money
supply, interest rates
and availability of
credit).
Reduction in inflation
Leads to increases
competitiveness,
cheaper exports & job
creation in the long run.
Co’s keep wage increases to
a minimum to avoid costpush inflation.
Laissez faire
•Minimum state
intervention
•De-regulation of
markets
•Privatisation
Supply side policies
Improve market
efficiency, boost
supply, reduce the
power of trade
unions.
Control of money supply
Control inflation by strict
control of money supply.
Restrict loans & high interest
rates.
The Shock Doctrine
Advisor to Nixon, Pinochet, Thatcher, Regan & GW Bush Jnr
Are We Witnessing the Shock Doctrine in Effect?
Milton Friedman debates Naomi Klein
Other Modern Economists
• Supply-siders
• J. K. Galbraith (1908-2006)
Supply-sider theorists
Late 20th Century
1. Economy developed by stimulating the supply of goods.
2. Reduce taxes, encourage work, investment &
government revenue.
3. Deregulation & privatisation encourages competition,
increase word production & reduce prices.
• Controversial because it advocates reduction of higher
rates of tax which benefits the wealthy.
• However supply siders claim that reducing tax rates will
lead to increased tax revenue.
• This is because increasing tax rates is a disincentive to
work & invest.
J. K. Galbraith
Maverick
Keynesian/liberalist
(1908-2006)
• Wrote the book
“The Affluent Society”.
• Recommended that
governments should increase
tax to reduce conspicuous
consumption.
• Warned of economic power of
multinational oligopolies.
